1. Characteristics of Life

2. What characteristics do all living things have in common?
Is it alive?
What characteristics do all living things have in common?

4. What Do Living Things Have in Common?
Made of cells

5. Made of Cells
All living things contain one or more cells with genetic material (DNA)
Cells are organized into structures that carry out certain functions
Cell -> Tissue -> Organ -> Organ System -> Organism

7. What Do Living Things Have in Common?
Made of cells
Require Energy

8. Require Energy Living things must get energy to live
Autotrophs-make their own energy (like plants)
Heterotrophs-eat other organisms to get energy

9. What Do Living Things Have in Common?
Reproduce

10. Reproduce
Living things must make more living things for their species to survive and their genetic material to be passed on to the next generation.

11. What Do Living Things Have in Common?
Reproduce
Grow

Made of cells
Require Energy
Develop

12. Growth and Development
Growth-increase in the amount of living material and the formation of new structures
Development-all the changes that take place during the life of an organism

13. What Do Living Things Have in Common?
Reproduce
Grow
Adapt and Evolve

14. Adapt and Evolve
Adaptation-an inherited structure, behavior, or internal process that allows an organism to respond to their environment and live to reproduce
Evolution-gradual changes in a species through adaptations over time

15. The Characteristics of Life
Things must have ALL of the following to be considered alive:
